The 2025 Polaris Boost PRO RMK 155 isn’t just a snowmobile—it’s a specialized mountain assault vehicle, engineered for the riders who demand maximum output, precision control, and the kind of backcountry capability that makes the impossible feel routine. This sled is the culmination of Polaris’ relentless innovation in high-altitude performance, chassis design, and rider-centric technology.

At the heart of the Boost PRO RMK 155 is the Patriot Boost engine—Polaris’ own factory-installed turbocharger, seamlessly integrated to provide crisp, instantaneous throttle response with consistent power delivery from sea level to the highest peaks. There’s no lag, no guesswork, just explosive performance that’s ready the moment you squeeze the throttle. For mountain riders tackling steep ascents, tight trees, or bottomless powder, that kind of precision can mean the difference between control and chaos.

The MATRYX RMK chassis, a product of years of feedback from elite riders and rigorous testing in real-world conditions, brings balance and predictability to even the gnarliest terrain. Its narrow profile, sculpted ergonomics, and optimal weight distribution allow you to stay light on your feet and fully in control of the sled. The 155-inch Series 8 or 9 track strikes the perfect compromise between float and maneuverability—short enough to flick around tight zones, long enough to provide traction when you need to climb high and deep.
